For all my designs I use a button board with a voltage divider and A couple of buttons to control.
mostly I did this on trough hole board so I thought why not make a universal version of the board.
In some designs I use 4 buttons on the board, for others I need the fifth button.

This board can be used for the PLL controller, ATV reciever and the video router.
I will publish new software so all the the hardware will work with this board.

Buttonboard connections

Some designs use 5 buttons others only 4.
